GVP A4008 SCSI controller speed?

[amiadudeorwat]

Well, 3.9 would be ideal however it does not support the video toaster so I'm going to have to stick with 3.1 I use 3.9 for when I'm not using the Toaster and just want to play games.

Wait... what?  I have a 3.9 system that works with a Video Toaster, had two but I think I let the smoke out of the Toaster 4000.  I know there's a reaction/whatever the other one is called in that the Toaster 4.3 install breaks some libraries but I just copy the whole libs: devs: storage/ and locale/ dirs back over and it works again.  

On the topic at hand the A4008 has always been finicky for me about termination also there are a couple jumpers on it that I can't find doc on(lost mine long ago), but there's this story about the older GVP SCSI+8 burning a trace on the daughterboard, makes me nervous about playing the jumpers on the A4008.

Do this from a CLI prompt:
version gvpscsi.device

You can also try the mounter in sys:tools/ change the tooltype to DEVICE=gvpscsi.device

When you open it after setting the tooltype see if it trys to scan 0-6 or crashes?

Something to try is getting the binddrivers version 4.15 of the gvpscsi.device from Ralph Babel's site, put it in sys:expansion on your OS39 drive.  I'm not sure if that will override the one on the board but you should be able to remove the ROM from the socket on the A4008 as well.  Binddrivers will then load the gvpscsi.device instead of the older one on the ROM.

The gvpscsi.device isn't NSD compliant so you want to use PFS in direct SCSI mode.  Or you could use the old direct SCSI version of SFS.

If you're using ClassicWB then yeah PFS is in the Myfiles/Install/Largehd directory where SFS is.  The docs are in there too.  You'll need to do what you did with SFS at some point and select the PFS driver you want in HDtoolbox enter a dostype and copy the pfs-handler to L:   Remember to follow the PFSds instructions.
